Based on one of Hamilton's most radical designs, the Chrono-Matic 50 LE is utterly unique, and utterly Hamilton. Created 50 years after the creation of the Caliber 11, one of the first automatic chronograph movements, and based on the Chrono-matic Countdown, which is now a rare and highly collectible vintage piece, the new watch brings the adventurous and innovative spirit of the original into the 21st century. Sized the same at a whopping 48mm, the radical case design features two crowns, and three colored pushers.

While the overall aesthetic is largely the same, the Chrono-Matic 50 does feature some significant changes. The red pushers start, stop and reset the chronograph. The black pusher at ten changes the date, featured in a window at six o'clock. The crown at eight adjusts the internal bezel, found between the tachymeter and the main dial, providing count-down functionality. 

Inside of the Chrono-Matic 50 is the H-31 Swiss-made caliber. This automatic chronograph is based on the venerable ETA/Valjoux 7753, the H-31 features 27-jewels, hacking, hand-winding, pusher-set date, a frequency of 28,800 bph, and a power reserve of 60-hours. Most mechanical chronographs top out at around 40 hours, making the H-31 a unique caliber.
